Abstract : This in-house study was conducted to determine the acceptability and operational effectiveness of an experimental system for displaying and distributing satellite imagery designed for flight service station (FSS) application. Primarily, consideration was given to the efficacy of the displayed data, together with the presentation format used for the demonstration. Secondly, man-machine relationship and some software aspects were tested and evaluated. Interim results indicate that the prototype system provided graphic data in a form suitable for use by preflight, in-flight, and en route flight advisory specialists for nearly all their briefing functions. Equipment configuration, assembled for this evaluation/demonstration, proved reliable and acceptable (though not necessarily optimal) by the specialists participating in the demonstration. Conditional acceptability included display medium and size, graphical quality and information presentation, and associated software programs for accessing the data through the prototype system. It is recommended that a field study be conducted as Phase II of this evaluation. (Author)
